CYP2D6活性降低的女性内昔芬浓度较低,他莫昔芬的长期获益可能较差。我们在一个前瞻性队列中研究了CYP2D6基因型与他莫昔芬诱导的潮热之间的关系。我们收集了297名开始服用他莫昔芬的妇女12个月内潮热的频率和严重程度的数据。我们使用AmpliChip CYP450 Test进行CYP2D6基因分型,并将CYP2D6和他莫昔芬诱导的潮热中的遗传遗传多态性相关联。在他莫昔芬治疗4个月后,中间代谢者的平均热潮红评分(44.3)高于弱代谢者(20.6,p=0.038)或快代谢者(26.9,p=0.011)。在4个月时,我们观察到弱代谢型患者的严重潮热趋势比中间+快代谢型患者更少(p=0.062)。CYP2D6活性可能是他莫昔芬诱导的潮热的适度预测因素。是否出现潮热不应用于确定他莫昔芬的疗效。
Women with reduced CYP2D6 activity have low endoxifen concentrations and likely worse long term benefits from tamoxifen. We investigated the association between CYP2D6 genotype and tamoxifen-induced hot flashes, in a prospective cohort. We collected hot flash frequency and severity data over 12 months from 297 women initiating tamoxifen. We performed CYP2D6 genotyping using the AmpliChip CYP450 Test and correlated inherited genetic polymorphisms in CYP2D6 and tamoxifen-induced hot flashes. Intermediate metabolizers had greater mean hot flash scores after 4 months of tamoxifen therapy (44.3) compared to poor metabolizers (20.6, p=0.038) or extensive metabolizers (26.9, p=0.011). At 4 months, we observed a trend toward fewer severe hot flashes in poor metabolizers compared to intermediate plus extensive metabolizers (p=0.062). CYP2D6 activity may be a modest predictive factor for tamoxifen-induced hot flashes. The presence or absence of hot flashes should not be used to determine tamoxifen's efficacy.
